Jeff you nailed it, the core area. You read that article in D&DH about how some mature bucks are just so lazy the even during the rut they won't leave their core area?
Yep. And I was surprised to find out just how small these areas are....and how small they become as he ages. I was also intrigued when they said it could "shift"....even just a hundred yds or so in one direction from year to year.
Makes me think we'd better know where they live....and know damn well.....if we think we're gonna kill a really old deer.
Or...catch him chasing tail.
